Title: Improvements in coin freed amusement apparatus
IPC: G07F17/38
Filed: 1929-01-14
Abstract: .325,353. Bradshaw, G. Jan. 14, 1929. Coin action, multiple-coin; Tivoli billiards and the like.-To use the machine, two or more coins are inserted, one or all of which are returned to the player at the end of the game. In apparatus in which two coins are necessary, the first coin passes down a shoot 7 and rests on the end of a lever 13 projecting into a returned-coins shoot 61. The weight of the coin pivots a tongue 8 which deflects the second coin so that the latter rests on the ends of two pivoted levers 17 situated at the junction of the shoot 61 and a retained-coins shoot 60. The weight of the second coin pivots the levers 17 and so moves a catch 24 to allow a ball to roll on to a track 26. The ball is propelled round a heart-shaped track 4 by operating a lever 48. Two sets of ball pockets 31. 32, 33 are provided. Should the ball miss all pockets it runs on to a track 26 on the other side of the machine so that it can be propelled by another lever 48. If the ball passes into one of the end pockets 32 or 33 it runs down a track 29, strikes the end of a lever 37 which retracts the lever 13 to allow the first coin to pass down the shoot 61, and retracts one of the levers 17 to permit the second coin to fall down the shoot 60 to a cash box, and is finally held by the catch 24. If the ball falls into one of the middle, pockets 31 it runs down a track 28 and depresses a lever 35 so as to retract the lever 13 and the second lever 17 so that both coins are returned to the player down the shoot 61. The track 4 may be resilient.

IPC: G10K1/34
Filed: 1952-01-17
Abstract: 716,731. Thermionic-cathode tubes. MINISTER OF SUPPLY. Jan. 15, 1953 [Jan. 17, 1952], No. 1415/52. Class 39(1) [Also in Group XXXVIII] A transducer producing electrical variations corresponding to variations in external pressure comprises a thermionic diode valve whose cathode is fixed, and whose anode is attached to a flexible membrane, whereby variations in pressure alter the distance between the electrodes to vary the impedance of the valve, which may be measured by means of a phantastron circuit. Construction. A glass valve envelope 1 (Fig. 1) closed by a flexible copper, aneroid diaphragm 2, contains a heater 10 and cathode 9, surrounded by a ring member 12 which prevents the diaphragm from touching the cathode. The diaphragm 2 is biased upwardly by a spring strip 15, located by a threaded stem 16 attached at the centre of the diaphragm and held in tension by a nut and collar 19, the diaphragm being normally a short distance from ring 12. Reduction of the external atmospheric pressure causes the diaphragm 2 to move away from the cathode 9, thereby changing the impedance of the valve. Measuring atmospheric pressure. The transducer 21 (Fig. 4) forms part of a potentiometer 22 controlling the anode voltage of a pentode valve 25 arranged as a phantastron, so that a pulse applied at the SYNCH terminal 26 initiates a phantastron cycle, producing an output pulse at terminal 27 whose length is proportional to the anode voltage, and may be measured. The apparatus may be attached to a radiosonde balloon.

Title: Improvements in or relating to the treatment or regeneration of gas-scrubbing liquids
IPC: C10K1/12
Filed: 1937-01-18
Abstract: <PICT:0488951/III/1> An unconcentrated spent gas-washing liquid containing ammonium carbonate and ammonium hydrosulphide is, before removal of hydrogen sulphide, treated in concurrent flow with carbon dioxide and hydrogen sulphide removed from a previously treated portion of spent liquid.  The apparatus may comprise three bubble cap plate chambers 16, 17, 18, liquid from a gas washer 11 passing in succession therethrough and returning to the washer through a cooler 19.  A mixture of carbon dioxide and hydrogen sulphide entering chamber 16 through pipe 21 converts the liquid to ammonium bicarbonate and ammonium hydrosulphide, surplus gases passing through pipe 22 to a kiln for conversion to sulphur.  The liquid may be dephenolized before delivery through a pipe 24 into chamber 17 in which it is treated in countercurrent by a gas rich in carbon dioxide from the third chamber, the effluent liquid consisting chiefly of ammonium bicarbonate.  In chamber 18, the liquid is heated by a coil 32 to a final temperature of about 102 DEG  C. and then passes through exchangers 30, 27 to heat the liquid flowing to earlier stages of the chamber.  The ratio of free ammonia in the washing liquid to ammonia present as ammonium carbonate is desirably between ,8 : 1 and 1,35 : 1.  Liquid leaving the third stage is suitable for the production of concentrated ammoniacal liquor.

Patent GB-565179-A (GB)
Title: Manufacture of cellulose mixed esters
IPC: C08B3/18
Filed: 1943-01-29
Abstract: Cellulose mixed esters are obtained by processes in which the esterification reaction is carried out in the presence of a stable chlorofluoro-hydrocarbon.  The halogenated hydrocarbon enables the reaction to be readily carried out without overheating and at a desired temperature, since the vaporization of the halogenated hydrocarbon takes up the heat of the reaction. Trichloro-fluoro-methane, b.p. 23.7 DEG  C., dichloro-difluoro-methane, b.p. 29.8 DEG  C., dichloro-monofluoro-methane, b.p. 8.9 DEG  C., dichloro-tetrafluoro-ethane b.p. 3.5 DEG  C., or trichloro-trifluoro-ethane b.p. 47.7 DEG  C. may be used. Esterification may be carried out in the presence of sulphuric acid as catalyst, and the operating temperature may be maintained within the range of 5-50 DEG  C.  The process may be used in the production of cellulose aceto - butyrate, aceto - caproate, or aceto - stearate. In an example, cotton linters are mixed with acetic acid and then with butyric anhydride, acetic anhydride, trichloro-fluoromethane and sulphuric acid.  The reaction is carried out in a vessel with reflux condenser and the halogenated methane which condenses is returned to the mixture.  Before precipitating the cellulose ester from the mixture, the trichloro-fluoro-methane is removed by atmospheric and vacuum distillation.  In another example, the reaction mixture comprises cotton linters, acetic acid, acetic anhydride, caproic acid, trichloro-fluoro-methane and sulphuric acid.
